When xenstat library parse /proc/net/dev, it uses strpbrk function to get pointer to device name. However, it miss capital letters in the array of valid characters so it get incorrect name in case device name starts with capital letters or even segfault if it contains only capital letters. This patch adds missing characters to strpbrk call. Signed-off-by: Miroslav Rezanina

Full_Name: Roger Bivand Version: 0.99.0 OS: RH Linux 6.1 Submission from: (NULL) (158.37.60.152) I am working on an interface between R and the GRASS geographical information system, written in R, with no dynamically loaded code. I have written full examples, and tested then under R 0.90.1, both by entering example() for each function and R CMD check, both of which worked without problem. Under

Nice! This looks good to me but probably Chris or someone else should sign off on it. There were two minor warnings on Darwin: -- In file included from /Volumes/Data/Users/ddunbar/llvm/lib/Support/regexec.c:81: /Volumes/Data/Users/ddunbar/llvm/lib/Support/regengine.inc: In function 'sbackref': /Volumes/Data/Users/ddunbar/llvm/lib/Support/regengine.inc:665: warning: control reaches end of

I think having this logic buried within libhid/libusb (libusb:libusb_open(), line 179 to 206) is ultimately a mistake, albeit one that I am probably responsible for. Would it make sense to confine libhid to low-level operations, and leave the decision of trying to reopen vs. retrying to open to the high-level driver, in this case usbhid-ups? I envision that the code in usbhid-ups:reconnect_ups()

Hi, In R 3.4.0, the "Pattern Matching and Replacement" documentation that describes regexec(), gregexpr(), etc. states that the "text" argument to regexec is a character vector, "or an object which can be coerced by as.character to a character vector": regexec(pattern, text, ignore.case = FALSE, perl = FALSE, fixed = FALSE, useBytes = FALSE)

Hi, I know that Asterisk doesn't support Instant Messaging, but I'm trying to use the AGI function RECEIVE TEXT to implement a kind of IM service. I have a sip softphone that tries to send a message to an active channel and the AGI script that expect to receive the text through the STDIN. Two problems arise: First: How can I say to asterisk to get the message? (I see on CLI console that

FWIW I was able to replicate the problem using AIX7.1 on Power8, R 3.2.3, vac/xlc 11.1, xlf 13.1 in 64-bit mode. Indeed, Peter's analysis is correct re_regexecb(&regline, line..) returns REG_NOMATCH even though the string is literally "Package: tools" - no special characters anywhere.

I've just tried using both Duncan's RSPython and Walter Moriera's rpy with R 1.5.0. Both segfaulted during startup in exactly the same place, apparently while trying to load the ctest package. Recompiling the packages doesn't seem to have any effect on this outcome. Here's the first few lines of a gdb backtrace: #0 0xff132df8 in strlen () from /usr/lib/libc.so.1 #1

A very common use case for regmatches is to extract regex matches into a new column in a data.frame (or data.table, etc.) or otherwise use the extracted strings alongside the input. However, the default behavior is to drop empty matches, which results in mismatches in column length if reassignment is done without subsetting. For consistency with other R functions and compatibility with this use

Changing the default behavior of regmatches would break its use with gregexpr, where the number of matches per input element faries, so a zero-length character vector makes more sense than NA_character_. > x <- c("John Doe", "e e cummings", "Juan de la Madrid") > m <- gregexpr("[A-Z]", x) > regmatches(x,m) [[1]] [1] "J"

Thanks for your help Duncan. Your last comment helped me to figure out what FreeBSD was doing differently than Linux/Solaris. This fix worked on a machine with Python 2.1, R 1.3.1 and FreeBSD 4.1. Here are the details: The pthreads fix: I added '-lc_r' to the PKG_LIBS definition in src/Makevars.in. The FreeBSD 'man pthread' page suggests that adding -pthread to the gcc statement

if you want "to extract regex matches into a new column in a data.frame" then there are some package functions which do exactly that. three examples are namedCapture::df_match_variable, rematch2::bind_re_match, and tidyr::extract. For a more detailed discussion see my R journal submission (under review) about regular expression packages,

A question for a (experienced) user of the RPython package on linux. I'm trying to call R from python on a linux (Suse 7.3) box. After installing R CMD INSTALL -c RSPython_0.5-2.tar.gz I start python and do: >>> import sys >>> sys.path.append('/usr/local/lib/R/library/RSPython') >>> sys.path.append('/usr/local/lib/R/library/RSPython/Python')

After some discussion within R core, we decided that a "nomatch" argument on regmatches() may be a good initial step. We might add a new function later that combines the regexpr() and regmatches() steps. The gregexpr() and regexec() inputs are both lists so it's not clear whether a "nomatch" value would be relevant (the elements are empty) in those cases. On Mon, Sep 2,
